This device often is installed on check valve, hose pipeline also release certain hydraulic pressure. Pipe Resonance Apart from hydraulic stock, other hydraulic components also cause a certain degree of noise in pipeline, such as vane pump, overflow valve, vapor separator, measurement transducer, solenoid valve and nozzle. Sometime pipe resonance will be generated if the inherent frequency of pipe equivalent to hydraulic pulse resulted from hydraulic components of fuel dispenser. At that time, the normal working state will be affected, which is harmful to staff’s health due to intensive noise. In order to explain this problem, the inherent frequency of pipe is introduced here. Pipe inherent frequency is: ω0 = kπ/2 l2 ·EJgGd+Gj (2-14) In the above formula: ω0 ── inherent frequency of pipe l ── supporting point distance E ── elastic mo fuel dispenser dulus of pipe material J ── inertial moment of pipe section g── acceleration of gravity Gd── weight of pipe per meter Gj──liquid weight in per meter of pipe K── modifying coefficient K= 1-pA+mv/2π2EJA/l2 (2-15) In above formula: A ──pipe section m ──liquid weight in per meter of pipe v ──velocity of flow of liquid in pipe Several relative parameters affect the inherent frequency of pipe in Formula 2-14. Therefore, most manufacturers pay much attention to these elements that affect pipe inherent frequency and pulse frequency of hydraulic components in the design and manufacture of fuel dispenser, making the two frequencies as much different as possible so as to appear pipe resonance in fuel disp fuel dispenser enser. 3. Hose used for fuel dispenser There are two kinds of hose used in fuel dispenser. one is made according to GB/T10543 Rubber Hose Used for Refueling and Discharge of Airplane, connected oil indicator with nozzle; the fuel dispenser other kind of hose is used in fuel dispenser with vapor recovery device, not only connecting oil indicator with nozzle,

ed Marxist regime trying to cement its hold over an intensely religious, impoverished and ill- educated populace. But it is a disappointment. Ethiopia s prime minister, Meles Zenawi, had been close to Britain s prime minister, Tony Blair, and a favourite of aid donors. His government has shown some leadership in reducing poverty, not least by extending the reach of primary schools, health clinics, electricity and roads. But the government s grip on power is slipping. An instinct for self-preservation may explain the former rebel fighters return to Soviet methods. Things began to fall apart last year when a disorganised opposition disputed the results of a general election. Street protests followed in the capital in June and again in November. Around 80 people were believed to have been killed, including some police, after which opposition leaders, journalists, human-rights fuel dispenser activists and businessmen were arrested. Many have since been charged with treason and genocide. The government promised a speedy trial but has reneged, dragging out the process while keeping it far from view. Most of those arrested are still languishing in Kaliti prison in Addis Ababa. The cells there are baking hot by day, freezing by night, infested with roaches and mice, and thick with mud in the rainy season. The government has so far used a mix of spin and harassment of journalists (local more than foreign) to avoid international condemnation. But that may be changing. An independent commission into the June and November killings has become an embarrassment. The government had stacked the commission with its supporters but eight out of ten of th fuel dispenser em still decided that the government had used excessive force. The commission members claim Mr Zenawi tried to get them to reverse their decision earlier this year; when that failed the government sought to bury the findings. fuel dispenser The head of the commission and his deputy fled to Europe, fearing for their safety. Their investigation says at least 193 people were killed, nearl
